and inherit from its global `Object` class.

However, the created `MessagePort` no longer inherits from

`transferList` may be a list of [`ArrayBuffer`][], [`MessagePort`][], and

`transferList` may be a list of {ArrayBuffer}, [`MessagePort`][], and

[`FileHandle`][] objects.

After transferring, they are not usable on the sending side of the channel

anymore (even if they are not contained in `value`). Unlike with

[child processes][], transferring handles such as network sockets is currently

not supported.

If `value` contains [`SharedArrayBuffer`][] instances, those are accessible

If `value` contains {SharedArrayBuffer} instances, those are accessible

from either thread. They cannot be listed in `transferList`.

`value` may still contain `ArrayBuffer` instances that are not in

#### Considerations when transferring TypedArrays and Buffers

All `TypedArray` and `Buffer` instances are views over an underlying

`ArrayBuffer`. That is, it is the `ArrayBuffer` that actually stores

All {TypedArray|Buffer} instances are views over an underlying

{ArrayBuffer}. That is, it is the `ArrayBuffer` that actually stores

the raw data while the `TypedArray` and `Buffer` objects provide a

way of viewing and manipulating the data. It is possible and common

for multiple views to be created over the same `ArrayBuffer` instance.

Because object cloning uses the [HTML structured clone algorithm][],

non-enumerable properties, property accessors, and object prototypes are

not preserved. In particular, [`Buffer`][] objects will be read as

plain [`Uint8Array`][]s on the receiving side, and instances of JavaScript

not preserved. In particular, {Buffer} objects will be read as

plain {Uint8Array}s on the receiving side, and instances of JavaScript

classes will be cloned as plain JavaScript objects.
